.ASH-DISCHARGE DEVICE FOR GAS-PRODUCER GRATES.

Application filed January 26, 1915.

vGas-Producer Grates, of which the following is the specification.

1n dry bottom gas producers of the kind which, in sectional plan, are considerably greater in length than in width, should combustion be more rapid within the producer at one part than at another, there is an uneven descent of ash to the lower part of the producer, and its removal is a matter of difficulty.

r1`his invention has for its object to provide for producers, of the type referred to, an improved ash discharging device, whereby any accumulation of ash at either the ends or the middle of the producer may be discharged without interfering with the other parts.

The producer is of ovoid form in cross section, that is to say oblong with rounded ends, or oval. t may be fitted with any suitable form of blower grate, but preferably of inverted truncated conoidal form with rounded ends and to some extent of the type described in the earlier Patent No. 1,065,315-dated 17th June, 1913, so that the grate follows the contour of the producer. Beneath this grate there is an ash table shaped to suit the cross section of the grate, and supported in the usual ash hopper. Extending longitudinally above this table is a shaft which carries plates or blades of a total length corresponding to the length of the table, and extending at right angles thereto. rllhese plates as a Whole conform in width and depth to the shape of the lower aperture in the grate or producer in which they work. That is to say, that while their lower edge is close to the surface of the table, their ends are curved to suit the lessening area of the ends of the grate. The plate, divided vertically into two or more parts, has one part hinged to the shaft, and

the other or others to a sleeve or sleeves thereon. The shaft and sleeve or sleeves, extend to the outside of the producer, and they may be rocked either by hand or mechanically, so that one or other part of the blade, or the blade as a whole, is so oscillated that the ash is forced over the sides of the table into the ash hopper.

An example of the improved ash removing device is illustrated on two accompanying sheets of explanatory drawings, Figure 1 Sheet 1 being a longitudinal sectional elevation and Fig. 2 Sheet 2 a transverse sectional elevation.

In this example the producer of ovoid form has an inverted conical blower grate A conforming to its outline in plan, and below the grate a usual ash table B. Longitudinally above the ash table B is a shaft C. This shaft is centrally supported by a bracket D on the table and passes out through stuffing boxes E in the casing of the producer. Fixed upon the shaft C, directly upon either side of the bracket D, are two parts F of the plate hereinbefore referred to. Beyond these on either side sleeves G embrace the shaft and pass out through the stuffing boxes E. On these sleeves are fixed two other plate parts H. On the projecting ends of the sleeves G and of the shaft D are handles J by which the several plate parts may be oscillated.

Wha-t I claim is 1. In connection with gas producer grates, an ash discharging device comprising a table beneath the grate a shaft above and parallel with the table, a sleeve rotatable on the shaft, a plate in parts on the shaft and on the sleeve and depending toward the table, and means for oscillating the shaft and sleeve.

2. 1n connection with gas producer grat-es, an ash discharge device comprising a table beneath and conforming in plan to the outline of the lower end of the grate, a shaft longitudinally above the table, stuffing boxes in the producer casing through which the shaft projects, a central support for the shaft, a sleeve in parts on lthe shaft and also name to'lthis specification, in the presence of passing oufl through the stung boxes, a two subscribing Witnesses. plate n parts on the sha-ftand on the sleeve and depending toward the table, and han- QUlNTIN.
